Size at Age Comparisons
Given that we can’t really construct meaningful VB curves for cohorts with a 10-year window of interest, we need to consider an alternative way of putting some statistics behind our numbers to assess significance.
I think looking at differences in LaA and WaA over periods of interest will be helpful. I think a useful example to emulate is Fig 3 and Table 1 in the attached Neuheimer and Gronkjaer paper. However, instead of using trend lines and slopes, it would be better to do a Welch’s t-test comparing 1970-2009 to 2010-2019 (and plotting means for those periods in the figure).
I’m also still debating whether to use 1970-2009 as the comparison or whether to do just the preceding decade, so seeing Welch’s t-test results for 2000-2009 and 2010-2019 would be helpful too.
Please truncate output values to no more than 3 decimal places so it’s easier to look at. (We’ll want to pull other stats out of the Welch’s t-test for the paper, but for shaping the paper, I’d prefer to see less right now.)
These are the methods to use for the tests and for testing assumptions:
Welch’s Two-Sample T-Test
Bartletts Two-Sample Test
Length at Age
The following tables display the results of two-sample testing comparing the length at age of each species between data from two different periods. Significant differences are highlighted when they occur, and in those rows the larger size period’s mean has been highlighted in green, with the smaller sized period’s mean highlighted in red.

Significant Growth Differences
With the exception of silver hake, all species in these tests are significantly smaller at older ages. There are instances where species are larger at their earliest ages (1-4 years of age), but their growth then plateaus and they ultimately reach a smaller adult size. Black sea bass is another possible exception, showing some age-classes with smaller lengths and weights, but not in a consistent pattern with increasing age.
The following two sets of figures display what the average length or weight was each year for a given species. Means have been overlaid for the groups of years we are comparing above.

Cohort Decadal Growth Differences
The following figures display what the average length or weight was for individuals born in a given decade. Means for each decade have been overlaid. No data for individuals born before 1970 were included here.
